Right, I've used my other two options now it's time to throw the question out to the audience, I now have a 350 Chev engine which I have to rebuild (my choice) and I'm going to glue it somehow on to a LT77 5 speed box again my choice, I've spoken to the insurance and also the state vehicle licensing after advice from another thread, emissions is an issue but as long as fit a four barrel Rochester I'm right, something I'm going to find at the local Kwicky Mart no doubt, insurance seems to hinge on getting the car over the pits so that's what i'm going to do.
The reason for the post is about who's adaptor kit do I use to glue one bit to the other, it seems to come down to two, both in Melbourne, I would like to learn from personal experiences and not hear say, good and bad, Ok fire away......... Keep the shiny side up

Mate used a Marks kit on his 4skinner conversion with VS V6 Commodore, he is up to $14,000 so far JUST ON THE CONVERSION and getting it sorted out!!!

Then there are some success stories with them... Its like Diesel V Petrol, Auto manual etc etc.. Good and bad in all.

Personally, I would go with a 4.4 Rover and no crappy conversion thing!!!

The 350's go well as a 383, Ask Cheezy! Wheelstands his GQ...

Truckster,
Thanks for the comments, I've read that the Holden conversion can cost S---t loads of cash with the fuel injection systems and how they are tied into the security system etc, I'm going for the long rebuild type option, as and when i get the bits great if it takes me twelve months I don't really care it's something to tinker with in the workshop, the old donk is going well and doesn't need to be changed at present. If I don't get out of this little jobbie finished and on the road for 4k I'll want to know why, if I want to finish it by Friday, back the truck up and tip the cash in. I'm sticking with the carby conversion even though this 350 was fitted with fuel injection, I've got to weld the two centre holes in an original inlet manifold and redrill them at a different angle or something, there also some issues with the starter motor hitting the diff housing and the dizzy hitting the firewall, sounds like fun and a bit of a challenge, the LT77 box will be the next thing to bite the dust so i'll stick a turbo 700 in and see what happens when that dies. No doubt as my threads unfold you will know where I'm up to. Taking the old girl over the pits will be a challenge I've got some other bits to fix before I do that.
I'm off to the the BFG M/T's a work out on Sunday the conversion may come round quicker than I planned......... catch you aroundKeep the shiny side up

I don't know the torque figures for the 350 but I suspect you will eat the LT77 gearbox. Go for the stronger LT95 or an auto.

Rod,
You're right, not quite double, I suspect it will be spat out and not just eaten. I'm not exactly Victor Bray so it should last a while as long as I'm careful, I might stick a turbo 700 in or something along those lines, I'll see what is available and how much cash I have.Keep the shiny side up

I was very surprised that your rego people will allow a simple carby swap to meet emmission's laws over there, but your luck i s'pose. I would use Marks adapters, but first get a catelogue to see what engine/trans combo's they actually do, it may pay to change the tranny first up, rather than find that an adapter is not available for the transfer, down the track. I know they do starter rotations and small/reduction starter kits, so that is not an issue. As I said before, it's all the little things that take the time. Have fun.

Steve,
Don't let me kid you I don't think it's going to be that simple, I've just mailed off a 14 page document all about the conversion to our local officer Dibble so he can tell me if I can or can't do the conversion, what he told me was that as long as the engine i'm fitting is the same age or younger that's ok, No Holleys because they aren't for street use, I have to fit a four barrel Rochester with emission control to get the pit pass, not that he was being specific or anything. As you say it's all fun. I would like to thank you for the help it was very useful and has pointed me down the right track. I've heard about the starters, the shorter Hi Torque starter should be the go, I've spoken with the company you mention and they have been more than helpful also getting me on the right track, I like to see the visual thing so I can get my head around exactly what's happening, i'm surprised they don't have pictures on the web site.
Thanks again for the help. Keep the shiny side up

Martyn,
I have done a 4.4l (P76) conversion to the 82 4speed Rangie that I had and was very happy with it. I ran dual fuel on it . I towed my caravan around Aust with it and had no trouble. I think this is a good choice of engine.
Both of my brothers did 350 chev conversions using home made adaptor kits into 5 speed manuals and both had overheating problems that caused no end of grief in spite of trying all sorts of fans and radiator swaps. Both sold their Rangies when they couldn't solve the problems. One also did in the weak Lt77 box but they are only good for 100 000km behind the 3.5l asthma pack engine anyway.
There is a lot of practical info at sandm.alphalink.com.au on engine swaps in Rangies including a V12 Jag engine if you're a real masochist.
Good luck
Trevor ( Perth)

Trevor,
Thanks for the comments, were your brothers running the standard radiators or someting else? I'm slowly getting more and more depressed about this conversion, I think I'm going to continue for now, "I've started so I'll finish", luck seems to be most people wishes so that bit's encouraging.
With the gearbox, the Rangie I have has 245K on the clock and it's going well so from your comment seeing as the box has done twice it's expected life I'm doing well. At this time I'm reluctant to change the box because of the extra fitting issues and more importantly cost, by the looks of things it's coming though.... Keep the shiny side up

Sam at Overkill engineering www.overkill4x4.com has a rangie with a 350 and T400 auto which goes ok.
the T400 is bulletproof and will handle alot more grunt than a t700.

my old man has fitted the 4.4 lt motor in his rangie with the wolf fuel injection kit some time ago. It goes well, with no hassles about parts fitting etc...

cheers

Martyn,
the radiators used on my brother's cars were original, and then replaced with 4 row heavy duty models. They tried various fan and viscous coupling combos including direct drive. they even cut extra louvres in the bonnet to try to shift more air.
I ran a standard radiator with my 4.4 motor but did add an oil cooler which made a big difference on a hot day.
Another good thing about this motor is that only an expert would pick it from the original, once you fit the alloy rocker covers from the 3.5 motor and restamp your original engine number on it all your licencing and insurance dramas disappear!
The only problem with the 4.4 motor is sealing the inlet manifold which I had trouble with until I had the manifold refaced.
One final point - if your gearbox has done that km then any more powerful motor will probably kill it. You can tell when it's going by putting the transfer box in neutral and then running the gearbox in each gear and listening to it. When you hear it talking to you, reach for the bankcard!
Happy Motoring Trevor (WA)
